TheB-24J 5FO flown by the crew in
Pueblo colorado was manufactured at the Ford Willow Run plant in Michigan
and had an Emerson Electric A-15 Nose Turret. The cutaway above shows a Consolidated
A-6A hydraulically-driven tail turret installed in the nose in place of the
Emerson turret, typical of Liberators manufactured at the San Diego Consolidated
plant.

Specifications
of B-24J Liberator:

Powerplant:
Four Pratt & Whitney R-1830-65 Twin Wasp fourteen-cylinder air-cooled radial
engines with General Electric B-22 turbosuperchargers rated at 1200 hp at
2700 rpm for takeoff and maintaining this power as a military rating up to
31,800 feet.

The B-24L was an attempt to reduce
the increasing weight of the Liberator as more and more armament, equipment,
and armor had been added, with no corresponding increase in engine power.
The B-24L deleted the Sperry ball turret on most models and replaced it with
manually-operated twin 0.50-inch machine guns fitted to a ring mount and fired
through a ventral hatch behind the bomb bay. The
also replaced the Consolidated A-6B tail turret with the new M-6A "Stinger"
tail turret (manually operated with a wider field of fire) which was lighter,
having no hydraulics.
The crew's tail gunner, Charlie Laynor, remembers
operating the Stinger.
